Anti-static additive for conductive melamine resin with maintained durability and color


TUBALL™ graphene nanotubes are a high-performance anti-static agent for melamine systems that avoids the frequently faced side-effects of standard conductive filler on durability and color of the final product.

Anti-static agents: traditional vs TUBALL™

Thanks to their unique properties, graphene nanotubes (SWCNT) create a conductive, flexible, strong skeleton inside thermoset resins at extremely low concentration in comparison with most standard ESD additives.

For easy adaptation to a standard manufacturing process, OCSiAl has developed the TUBALL™ MATRIX line of industry-friendly concentrates. The ultra-low working loading – starting from 0.1% in the overall compound weight – has a minimal effect on other key properties and results in the cost-efficiency of this anti-static solution.

The most important characteristics of nanotube concentrates for use as an anti-static masterbatch in melamine formulations are:

  • Extremely low loading required to get a full range of conductivity
  • Stable conductive properties throughout service life
  • Simple adaptation of existing production processes thanks to a user-friendly concentrate form
  • No negative influence on original color and durability of end product
